2Claims.

One object of this invention isto provide a plaited silk lamp shade of improved construction.

Another object of the invention is to provide 5 an improved method of manufacturing plaited silk lamp shades.

Heretofore, in the manufacture of such lamp shades the plaited silk covering has ordinarily been sewn by hand on strips of material wound 10 about the upper and lower bands of the frame, which method has been slow, costly, lacking in uniform results, and dependent on the widely varying skill of specially trained workers.

According to the present invention the plaited 15 silk covering, as well as the lining, can be applied quickly, inexpensively and accurately, with uniform results, and without requiring the services of specially skilled labor.

While the foregoing statements are indicative 20 in a general way of the nature of the invention, other more specific objects and advantages will be evident to those skilled in the art upon a full understanding of the improved method and the resulting product.

25 A preferred embodiment of the invention is presented herein for the purpose of exemplification, but it will of course be appreciated that the invention can be practiced and put into effect with various modifications which will come 30 equally within the scope of the appended claims.

In the accompanying drawing:

Fig. 1 is a side view of a plaited silk lamp shade constructed in accordance with the invention;

Fig. 2 is an enlarged fragmentary section through the upper edge of one side of the lamp shade, taken on the line 2-2 of Fig. 1;

Fig. 3 is a corresponding section which shows the plaited silk covering and lining before being secured to the upper band of the frame; 40 Fig. 4 is an enlarged fragmentary section through the lower edge of one side of the lamp shade, taken on the line 4-4 of Fig. 1;

Fig. 5 is a corresponding section, showing the plaited silk covering and lining before,being se- 45 cured to the lower band of the frame;

Fig. 6 is a plan view of the plaited silk covering after a strip of adhesive material has been- In proceeding to make a plaited silk lamp shade in accordance with the invention, the material from which the silk covering I is to be made is first plaited. One edge. ll of the covering in its plaited form is sewn at l2 to a strip l3 of adhesive material, with the latter projecting somewhat beyond the edge of the covering, as shown at ll in Fig. 6. The other edge ii of the covering is sewn 'at it to an elastic band l'l. After this has been done the 10 edge l5, together with the elastic I1, is uniformly stretched and sewn to a strip ill of adhesive material, with a portion IQ of the latter projecting somewhat beyond the edge l5 of the covering. This procedure results .in a plaited covering which has one edge longer than the other. The extent to which the edge I5 is enlarged will depend upon the taper of the frame to which the covering is to be applied, 'the edge l5 being made only enough longer than the= edge ll to'permit both edges to be positioned flatly against the upper and lower bands 20 and 2| of the frame, and all the plaits at right angles to such hands after the covering has been applied to the same.-

After the covering has been secured at its upper and lower edges to the strips l3 and I8 of the adhesive material the covering is applied to the frame of the lamp shade by sticking the upper adhesive strip l3 to the outer surface 22 of the upper band'20 of the frame and by sticking the lower adhesive strip I8 to the outer surface 23.0f the lower band 2| of the frame, with the intervening portion of the plaited silk cover Ill drawn taut. In sticking the adhesive strips l3 and I8 to the upper and lower bands the projecting margins II and IQ of the adhesive strips are folded about the edges of the bands and stuck to the inner surfaces 24 and 25 of the latter, producing a doubly tight and strong engagement with the bands.

After the covering it has been applied in this manner the lining 26, which has had strips 21 and 28 of adhesive material sewn at 29 and 30 to its edges, is similarly applied to the inside of 5 the frame, the adhesive strips 21 and 28 being stuck to the folded-back marginal portions II and IQ of the adhesive strips on the covering,

with the marginal portions of the adhesive strips sings 3| and 32 of braid or other suitable material can be applied to the upper and lower edges to complete the assembly.

While the strips l3, ll, 21 and 28 have been referred to herein as being of adhesive material, it will of course be appreciated that such strips may be plain and that the adhesive may be applied either to the strips or to the bands of the frame, as desired, at the time of assembly, whereforethislanguageasusedintheclaimsisintended to embrace all such methods of accomplishing the desired adherence.

I claim:

1. The method of manufacturing plalted silk lamp shades of the type having a frame composed of upper and lower bands of different diameters, which consists in plaiting the silk covering, securing one edge of the same to a strip of adhesive material, securing the other edge of the same to an elastic band, stretching the last mentioned edge and securing the same in its stretched condition to another strip of adhesive material, and sticking the adhesive strips carried by the covering to the upper' and lower bands of the frame of the lamp shade, with the stretched edge of the covering applied to the larger diameter band of the frame.

2. The method of manufacturing plaited silk lamp shades of the type having a frame composed of upper and lower bands, which consists in plaiting the silk covering, securing one edge of the same to a strip of adhesive material, securing the other edge of the same to an elastic band, stretching the last mentioned edge and securing the same in its stretched condition to another strip of adhesive material, securing the upper and lower edges of the lining to other strips of adhesive material, sticking the strips of adhesive material carried by the covering to the outer surfaces of the upper and lower bands of the frame of the shade, with the adhesive strips folded about the edges of the hands into adhering engagement with the inner surfaces of the latter, then sticking the adhesive strips carried by the lining to the folded-back portions of the first mentioned adhesive strips, with the second mentioned adhesive strips folded about the first strips, and then applying braid or other finishing material to the outer surfaces of the upper and lower edges of the assembly.
